In a little over two months Xamarin, .NET Rocks!, and Visual Studiotoured 18 cities across the country showing how awesome it is to create cloud connected cross-platform mobile apps with Xamarin and Azure Mobile Services. If you weren’t able to attend the tour don’t worry as you can now watch a full webinar recording of the presentation given on the tour. In this webinar I cover the basics of creating your first Portable Class Library to share code from a single project and use it on Android, iOS, and Windows platforms. Then I add in Azure Mobile Services to synchronize data between platforms and finish off them demo by implementing Twitter oAuth with just a few lines of C# code.
